The Compaq 260626-B21 is a dual-device EIDE cable assembly designed for Compaq EVO-series desktop and tower systems. This internal cable supports simultaneous connection of two PATA storage devices—typically a hard drive and CD-ROM or additional hard drive—to a single IDE controller channel. The cable features standard 40-pin IDE connectors with conductor layout compatible with Compaq's EVO form factors and motherboard implementations. EIDE (Enhanced IDE) supports data transfer rates up to 16.7 MB/s in UDMA mode, sufficient for legacy optical media and hard drive configurations common in late-1990s to early-2000s systems. Primary use cases include system builds, repairs, and upgrades for Compaq EVO desktops, particularly when restoring original dual-storage configurations. This refurbished unit has been tested and is guaranteed fully functional; available via quote.
